Reducing the NO3 is my homework.

[7thheaven]

Hi!

I have used zeovit system for 6month. but I do not think I feel the zeovit
system completely. Not zeovit system itself but I can not use zeovit well.
My SPS color's are not good. Some SPSs are maintained not bad, but Some
are still brown colors. I know the changing the color is needed more time.
but I think maybe there is some problem in my tank. Here is my SPEC of tank.

100 net gallon BB tank
use CO2, not UV,Ozonizer,PO4 reducer
250w AC 14K,and BLV10K
schuran 150 skimmer (wet skimming)
2 tunze 6100 with multi controller
1 liter of zeovit media
2 drops bak and food twice in a week
zeo start dosing 1.5ml each moring and evening 3 drops AA at night daily
zeospur2 and ME once in two weeks
3 on/off pump (eheim compact 300 80gph)and 2~3 times shaking media daily
5% water change in a week.
use RO water (not DI)
use zeo Carbon
I have about 20 SPSs and 3 Anthias,1 percular,a purple gobi and
feed flake food (not much) once in a day.

and here is my parameters with salifert test kit.
salinity 1.025
KH 7.4
CA 470
MG 1200
PO4 0
NO3 2

so I think maybe high level of NO3 is my problem.
I cheked RO water again. it points 0.5 with salifert.

If I can reduce the NO3 level to 0, I think I can have a good result.
and the key point of reducing it. the use of start dosing is important.(IMHO)

Could you advice to me about dosing?
I need your help.
thanks.

Hi Vince, let me start by saying that sequestered-nutrients pools will be different in different reefs of similar size, ie. there is variation in individual tanks, differing nutrient imports & exports, therefore, the results will differ on the timetable for all of us. I would add a canister DI filter to your water processing system. Completely clean your entire skimmer once every two wks for peak performance & maintaining that peak effeciency. Add a powerhead pump to your main tank for increased current, thus improving coral color & growth,while increasing the detritus carried to your overflows, & add one powerhead pump to your sump to keep detritus in the water column for the zeo-filter & skimmer to more effectively filter. Dose 1Cup of carbon. Dose one ltr of zeolites but increase your flow to 120gph[use a compact Eheim 600] with changing the stones every 4wks[not 6wks] for the next two months. Continue your present dosages of bak/food7. If possible, obtain Start2 & PM me for dosing. If not, dose Start1 1ml 3x's/day & pump clean the stones with each Start dose. Decrease your dosage of AAHC to 3 drops 2x/wk. Vince, if you can completely follow the above, you will see marked improvement in 2mos. Bob

Wow Thanks Bob~
Here is a Summary and question...
1. add DI
2. clean skimmer (NOW I clean the skimmer every or once in two days regulary)
3. Add a powerhead pump
(Do you think 2 6100 model is not enough for my tank.correct?)
4. add one powerhead pump in my sump
5. Dose 1ltr of carbon
6. increase the GPH in zeovit reactor pump (I have eheim compact 600 )
7. changing the stones every 4wks[not 6wks]
8. Continue your present dosages of bak/food7
9. obtain Start2 & PM you for dosing
(Unfortunately I can not get Start2.but I wanna test that it is good stuff. or
I will wait until the start2 is released)
10. dose Start1 1ml 3x's/day
11. pump clean the stones with each Start dose
(I do not get it. you mean "shaking"? before or after?)
12. Decrease the dosage of AAHC to 3 drops 2x/wk

Thank you for great tip and information. and PLZ reply to my question.

If other expert has a opinion, please tell me freely...

i dont understand y 2 6100's are not enough flow for him ?
Nick

2 x 6100 should be enough flow but it may not be depending on how the tank is setup, if there is no flow behind / under the rocks then it is not enough.

I like to keep at least 15cm of space between the back wall and the rock structure and also I prop the rocks up on a pvc frame and only place some rocks on the bottom in front to hide the gap. If the rocks are right on the bottom and the flow can't reach it so detritus can settle and decay there then you'll have problems no matter how high your turnover is.

I also like to keep lots of brittle stars to clean up between those nooks and crannies.

[nyfireman3097]

o ok gotcha i dont know how good it is to have a briitle star in a bb but i do

[Aged Salt]

Thnx. Timon for the complete explanation
Vince, remember your test is detectable & also we can not test for all forms of nutrients. Stir-up the stones[shake/pump] each time you dose Start1 for better coral coloration & more efficiency from your zeolite filter Bob

[7thheaven]

Thanks Bob~ I wil do that~

and thanks nyfireman3097,Orion76 :teleport:

[nyfireman3097]

lol no prob

Finally~~

I checked out NO3 level is close to zero...

I changed the zeovit media,and KZ carbon, syphoned the sediments in bottom,zeovit pump to eheim compact 600.
and installed the RI filters~~~
increased start1 to 1ml dosing three times in a day...

I think 3ml is too much in my tank. but it is not bad....skimmate things
are increased and my skimmer is very busy....

My mission is changed...

Maintain the NO3 and PO4 to zero~!!!

I expenct SPSs' coloration is much better.... :afro:

Thanks guy...

Zeovit is perfect..

[7thheaven]

Is it OK that zeovit pump goes on all day? not 3on/3off?

[Aged Salt]

Hi Vince, it is not a necessity for the zeo-filter to be cycled, but cycling does reduce nutrients better, initially, in a balanced manner over continuous use. Bob

[7thheaven]

Thanks Bob...

The cycling means about 3on/3off or zeovit media?

[Aged Salt]

Yes, Vince, once one is deep into ZEOvit method,[reserved-pooled nutrients depleted] it is fine to run the zeo-filter with the zeolites, continuously. Bob

[7thheaven]

I am so sorry Bob.....
My English is not good. so I do not understankd what you said fully...
Are you talking about changing zeovit media?
How about turning on pump 24/7?

so sorry..
